Radar Systems

Traana has several first to its credit in the domain of Radar Systems in India.

Traana was founded by Deepak K. Chandrasekaran. Deepak’s association with Radar Systems dates to design and development of the Indian Doppler Radar (INDRA). INDRA was a landmark project for India as it was the first ever large radar system designed and developed in India.

Traana is the first privately owned company in India to have designed and developed a fully indigenous Short-range Radar Surveillance System which has since been duly deployed on India borders.

Traana is the first private enterprise in India to have published and presented a Research Paper in an International Radar Symposium.

Collectively, we have more than 100-man years of experience in design and development of Radar Systems. Our primary expertise is in Digital Signal Processing (DSP), Detection & Tracking Algorithms, Radar data Processing (RDP), Radar Displays and Command Interfaces.

We have also done significant work in Radar Environment and Target Simulation Systems.

The expertise Traana has gained in Radar Systems and Technology may be further used to expand to Electronic Warfare

SSRS: Shortrange Surveillance Radar System

Fully indigenous Shortrange Surveillance Radar System (SSRS) provides 24x7 all-weather intrusion detection and alarm function for borders, large campuses, ports, airports, special economic zones, establishments, farmlands etc., through a series of short-range radar sensors networked to a single central command and control centre.

SSRS has the capabilities to detect, track (while scan) as well as automatically classify ground surface moving targets such as crawling man, walking man, cycling man, slow moving vehicle, fast moving vehicle.

Multiple selectable RF frequency spots ensure that different sensors do not interfere with one another.

The data processing capabilities of the system include Range, Doppler and Azimuth Centroiding, Track-while-scan processing as well as α-β Kalman filtering.

The built in GPS and digital magnetic compass, helps translating the target positions relative to the sensor to geographical lat-lon values – thus enabling the plotting of the targets on geographical maps using internet-based map services.

The system provides for a configurable alarm function – depending on the range and speed of the target the alarm gets triggered. The system has three types of alarms – audio alarm, visual alarm and network alarm.

The sensors are networked over Ethernet to the central command and control terminal. The Command and Control is provided through a GUI application that can run on any Windows/Linux based general purpose computers/laptops.

Desktop based Radar Environment & Target Simulator (RETS)

Testing and functional qualification of radars is an expensive and a resource consuming exercise, more so for airborne radars, easily running into millions of dollars over the development cycle of a new radar. Given that the radar theory and operation is built on probability and random processes, it is almost impossible to replicate the exact same radar environment conditions when detection and tracking algorithms are being developed and evaluated. A Radar Environment and Target Simulator (RETS) plays a key role in not only reducing the resources required, but also provides a repeatable scenario to help evaluate new algorithms. The RETS, for which Traana carried out the development work, provides a graphical interface allowing the user to create multiple scenarios consisting of multiple airborne targets, jammers and radars. Each such platform can be independently modelled by inputting various parameters such as the target cross section across different aspect angles, the radar transmission power, the antenna gain patterns, jamming techniques, etc., and, defining its trajectory of motion, graphically. The RETS operates in real time, simulating the RF echo parameters, such as the delay, the amplitude and the Doppler, from the different targets which can be used in BITE generation at different subsystem inputs.
